To wZZ whom it may concern:

Be it known that I, ANTHONY PULBROOK, solicitor, a subject of the Queen of Great Britain, residing at 8 Unwin Mansions, Queens Court Gardens,WVest Kensington, London, in the county of Middlesex, England, have invented certain Improvements in Inflatable Tires and Covers for the Same, (for which I have obtained patents in'the following countries: Great Britain, No. 15,172, dated August 8, 1894:; France, No. 237,516, dated April 3, 1894, and Belgium, No. 109,338, dated April 6, 1894,) of which thefollowing is a specification.

The outer tubes or coverings of inflatable tires are sometimes made of the skins of fishes or amphibious animals, thin leather-such as Wamba skin, deerskin, horse-hide, the grain part of pigskin, or other thick leather after strengthen them, and to increase their wearing qualities. For this purpose I treat them with a thin solution of balata, which penetrates every part of the skin or other material, and when dry I treat the "material again with the solution, and so on until the material is thoroughly iinpregnated With balata. The balata solution may be made with cold bisulfid of carbon or warm mineral naphtha; but I do not claim any particular method of making the solution, but use any known method.

I claim A material for use in the manufacture of pneumatic tires comprising skins, leather or similar material thoroughly impregnated With balata, substantially as described.

In Witness hereof I have hereunto set my hand in presence of two Witnesses.

ANTHONY PULBROOK.
